I have to wonder if Iran could try to deal with Pakistan for some of those nukes. I’m sure both sides would love to use them on us.
That would make Pakistan weaker vis-a-vis India.
They hate the Indians far more then they hate us.
So its possible but unlikely. Also the Paks are Sunni, so that’s another problem.
I prefer that Pakistan nukes Afghanistan. There’d be less Pakistani nukes and less Afghan Taliban.
